4 Claims.

My invention is an improvement in metallic receptacles and closures therefor and relates more particularly to means for eifecting a fluid tight seal between the closure and the recep and seal a cover on a receptacle, wherein means is provided for varying the sealing pressure about the ring subsequent to the initial contraction of the clamping ring.

Another objectbf my in ention is a clamping ring of the type described which is extremely simple of construction, durable and inexpensive to manufacture. I

Other objects and advantages of my invention will become more apparent from the following description of an embodiment thereof ref erence being made to the accompanying drawing in which like reference characters are employed to designate like parts throughout the same;

In the drawing:-

Figure 1 is a top plan view of an embodiment of my invention. b

Figure 2 is a fragmentary enlarged section through a portion of the receptacle, cover and locking ring taken on line 2-2 of Figure 1 and illustrates how the cover is seated on the receptacle to provide a liquid tight seal.

Figure 3 is an enlarged part plan view similar to that of Figure 1 and illustrates the ring ,on the receptacle in contracted position.-

Figure 4 is a view similar to that shown in Figme 3 except that the ring is illustrated in its normal uncontracted position.

Figin'e 5 is a sectional view taken on line 5-5 oi. Figure 1, with the cover and receptacle removed.

The embodiment of my invention herein illushated and described is particularly adapted for use in connection with metallic receptacles such as drums, barrels or the like, for shipping and storing oils or other liquids. Such containers or receptacles are subject to rough handlingand are usually made of relatively heavy gauge sheet to construct metal. It is therefore important that an ef-' fective seal between the cover and the receptacle be provided.

Referring now more particularly to the drawing which illustrates one embodiment of my,in- 6Q vention, the receptacle is-indicated generally at 1 and is provided at its open end with an annular bead 2 rolled outwardly. A cover 3 fits within the open end of the receptacle and is formed with an upwardly and outwardly extending an- (35 nular flange 4 which rests on a packing 5 supported on the bead 2.

The packing 5 may be made of any suitable flexible material and I prefer to use an annulus of rubber tubing as shown. It will be noted that 7 a portion of the flange 4 is curved in cross section to conform substantially to the curvature of the bead 2. the outer edge of the flange extending just short of a point opposite the greatest diam eter of the bead.

I. have provided means for seating the cover on the receptacle and pressing the flange of the cover and the bead together on the packing to insure a tight fluid proof seal therebetween. This means includes a contractible channeled 30 clamping ring 6 which is substantially U-shaped in crosssection, and in which the upper and lower walls are approximately parallel only for a short distance from their annular edges. Thus it will be seen that when the ring is assembled on the receptacle as illustrated in Figure 4, and contracted as in Figures land 3 a substantially vertical pressure is exerted by the inclined walls of the ring to press the flange and bead together.

Lugs '7 and 8 may be formed either integrally 9o with one of the walls of the U-shaped rin or separately and welded thereto. The lugs extend inwardly of the ring and may be raised'throughout a portion as indicated at 9.

I have also provided means for contracting the split channeled ring 6 which includes a lever 10 pivotally mounted on one of the lugs '7 by means of a pin 11. Thismeans also includes an adjustable connecting rod 12 slidably mounted in bearings 13 and 14 formed in the lug 8 by rolling over a portion of the lug material. The bearings are separated as at 15 to receive between 4 them an adjusting nut 16 which is threaded on the rod 12.- The outer end 0! the rod terminates in a bearing 17 for receiving a headed pin 18. Connecting links 19 and 20 are pivotally connected at one end to the pin 18 and at their opposite ends to the lever 10 by means of a pin 21. It will be observed that the lever lies in a plane between the links 19 and 20 and for the most part 10 ing the head and receptacle together when the ring is contracted. and means for contracting the preferably in a planeoutsi'de the upper wall of theme. Thelinklilalsoliesina planeoutside the upper wall 01' the ring by virtue of the bearing 17 and the spacer washer 22.

illustratedinFigure3,astraightline dra through the axes oi the pins 18 and 21 will lie between the axis or the pin 11 and the adjacent ring'section. In this way accidental release of arm terminates in a slightly curved face 24 for engagement with the upwardly extending wall of the cover flange 4.

As the lever is moved toward the position shown in Figure 3 the arm or shoe 23 engages the cover flange 4 and exerts in increased intensitya lateral. pressure on the flange wall and ring. The

application 01' lateralpressure in this way more uniformly distributes the clamping pressure on the flange and bead as the ring is contracted.

' In order to seal the ring against unauthorized removal, a tab 25 may be welded to. one of the ring walls as shown in Figure 5. i The tab is apertured to register with an aperture in the lever when the lever is in closed: position and a wire andseal may be applied in the usual way.

It will be noted that additional clamping or substantially axial pressure may be applied to the flange and bead after the ring is contracted, by simply turning the nut 16 to withdraw the connecting rod to the right in Figures 3 or 4. However, such adjustment may also be made while the ring is normally open as in Figure 4.

' Various changes may be made in the details or construction and arrangement oi! parts without departing from the spirit of my invention or thelscope oi the appended claims.

I claim:

1. A device for removably sealing a head on.

a metallic receptacle in fluid tight relation in cluding a contractible channeled ring for press- ,ring including a lever pivoted to a portion v the ring, links pivotally connecting another pertion of the ring with the lever and means for";

limiting the degree of contraction of the ring on the receptacle and head, said last named means including a lug carried by the ring and having 4 a rod receiving bearing formed therein, a threaded rod movable in the bearing and connected with the links, and a nut on said rod to adjust the same axially with respect to the bearing.

2: Adevice for removably securing a head on a metallic receptacle in fluid tight relation ineluding a split ring having portions for engaging the head and receptacle to pressthe same together, means for contracting and expanding the ring to secure or release the head on the receptacle, said means including a lever pivoted to [a portion or the rin a link pivotally connecting another portion of the ring with the lever. and

means for limiting the degree of contraction and expansion of the ring .on the receptacle and head,

I said last named means including a bearing member carried by a portion of the ring, a rod movable in the bearing and connected with the link,

and means associated with the rod to adjust the same within the bearing.

3. A device for removably securing a head on a metallic receptacle in fluid tight relation including a split ring having portions for engagement with the head and receptacle to draw the same tightly together, means for contracting and expanding the ring including a lever and a link pivotally connecting said lever with said ring,

and means connected with said link and said ring for selecting any one of a plurality of limits of contraction or expansion 01' said ring. a

4. A device for removably securing a head on a metallic receptacle in fluid tight relation including a split ring having portions for engaging the head and receptacle to press the same together, means for contracting and expanding the ring to secure or release the head on the receptacle, said means including a lever pivoted to a portion 01' the ring, a link pivotally' connecting another portion of the ring with the lever,

and means for limiting the degree of contraction.

and expansion of the ring on the receptacle and head, said last named means including a bearing member carried by a portion of the ring, a member movable in the bearing and connected with the link; and means associated with said movable member to hold the same within the bearing in an adjusted position.
